Created attachment 147098 [details] Compare quarter circle from custom shape with legacy circle The command X (ellipticalquandrantx) and Y (ellipticalquadranty) in a path are used for the rounded corner rectangle custom shape. They should provide a quarter circle in case of equal radii. But the used Bézier curves have bad parameters for their control points. The attached document shows the rounded corner rectangle in comparison to a legacy circle and legacy are. On the third page I have drawn lines as radius, to show without Bézier curves involved, where the outline should be. The solution has to be, that the custom shapes use for the X and Y commands the common tools from basegfx.

(In reply to Xisco Faulí from comment #1) > @Regina, do you plan to work on this ? In principle, I want to work on the problem. At the moment I am studying the code. This is not the only problem in this area. Since I still do not know when and in what order I will tackle the problems, I have not yet assigned the bug to me.
